ROTARY CARBURETER.

SPECIFICATION forming part of Letters Patent No. 787,254, dated April l1, 1905.

Application filed May 25, 1904. Serial No. 209,697.

Be it known that I. DAVID B. YOUNG, a citizen ot' the United States, and a resident ot' (`nlver, in the county ot' Marshall and State or' Indiana, have invented a new and Improved Rotary (`arbureter, of which the following is a t'ull, clear, and exact description.

Yl`h is invention relates to rotary carbureters, and has special reference to carbureters t'or use upon the intake-pipes ot' gasolene or oil engines.

A principal object ot the invention is to provide a carbureter of simple and inexpensive construction which may be applied to the intake-pipe ot' a gasolene-engine and which will be operated by the passage ot' the mixture ot' air and gas therethrough to etlect pert'ect and lunnogeneous mixing' of the air and hydrocarbon vapor which Vtorni the ingrcdients ot' the explosive mixture to be ignited in the cylinder ot' the engine.

One embodiment of the invention will be hereinafter described in detail, and the scope ot' the invention will be clearly pointed out in the appended claims. It is, however. to be understood that the structure described is only a typical embodiment ot' the invention, and changes therein may be made within the scope ol the claims without departing from the spirit ot' the invention or sacrificing the advantages thereof.

Ketel-ence is to be had to the accompanying drawings` forming a part ot' this specilication,

in which similar characters of reference indil cate correspoiuling parts in all the views.

Figure I is a longitudinal sectional view through the carbureter and adjacent sections otl the intake-pipe ot' an engine. Fig. 2 is an end view ot' the carburetor detached from the intake-pipe. Fig. 3 is an end view of the carburetor with the end cap removed. Fig.

preferably of about one inch greater diameter than theintake-pipeot the engine. The shell or casing I of the carbureter is provided at the ends with caps Q 2, preferably threaded on the shell or casing l and adapted to receive sections 3 3 ot' the intake-pipe ot' the engine. ln the ends ot' the shell or casing i suitable supports i are provided for a shaft 5, disposed axially within the shell or casing 1 ot' the carbureter. The supports l may be otl any suitable structure; but they consist, preferably, of plates of metal provided with a plurality ot apertures 6 t'or the passage ot' the gas and air and having an externallythreaded tlange T at the periphery for engagement with threads formed in the interior ot' thc shell or casing l, as best shown in Fig. l4 One ot the plates l has a threaded aperture in the center to receive the threaded end ot' the sha't't 5, and the other plate a is provided with an unthrcadcd opening to receive an unthrcadcd end ot' the shat't Upon the shat't 5, between the supportingplates et, there are mounted a plurality ot' tanwheels S and 8a ot special construction. Each ot these tan-wheels consists, preferably, ot' an elongated hub E), through which the sha't't 5 passes, .a plurality ot inclined blades or vaues l() or IO, and a peripheral rim 1'I,lormed with a slight t'orward taper. The wheels S have their blades or vanes I() inclined in the same direction, while the wheels S" have their blades or vanes lo inclined in the opposite direction. As the wheels 8 and 8 are alternately arranged, the passage ot' the mixture of air and vapor through the carbureter will cause alternate wheels to rotate in opposite directions. Thcspeed developed in the wheels will depend upon the rate ot passage otI the mixture ot' air and vapor, as will otl course be understood; but with an ordinary engine taking gas at its full capacity the intake-pipe andthe parts ot' the carburetcr should be so proportioned that the wheels within the carburetor will make about lifteen hundred revolutions per minute.

The rapid revolution of the Ylan wheels within the carburetor develops a considerable centrifugal tendency in the mixture of air and gasolene vapor, and to counteract this centrifugal tendency the rims l1 are tapered forwardly, as shown. The amount of the taper is determined by the rate at which the Wheels are intended to turn within the shell or casing of the carburet'er, as will be readily understood, and in the form of the invention illustrated the taper is adapted for a rotational speed of fifteen hundred revolutions per minute.

As will be readily understood from the foregoing description and the accompanying drawings, the carbureter having alternately-arranged fan-Wheels revolving rapidly in opposite directions is adapted to produce an exceedingly thorough and uniform mixture of air and hydrocarbon vapor,yvliich is, in effect, a true gas of homogeneous composition and is adapted to explode in the cylinder of an engine with very complete oxidation of the hydrogen and carbon present therein.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. rIhe combination of a shell, a stationary shaft axially supported therein, and a plurality of wheels rotatably mounted upon the shaft, and constructed of inclined blades and forwardly-tapered peripheral rims.

2. The combination of a shell, a stationary shaft axially disposed therein, and a plurality of Wheels rotatably mounted upon the shaft, and constructed of blades and peripheral rims, the blades of alternate wheels being inclined in opposite directions to the operative planes of the Wheels, and the rims of all the Wheels being tapered forwardly.

3. The combination with a substantially cy-` lindrical shell, of plates mounted in the ends thereof, each formed With a plurality of apertures, a shaft rigidly supported by said plates, and a plurality of Wheels rotatably mounted on the shaft, and constructed of blades and peripheral rims, the blades of alternate Wheels being inclined in opposite directions to the planes in which the wheels are disposed.

4. rIhe combination with a cylindrical shell, of plates mounted in the ends thereof, each formed With a plurality of apertures, a shaft rigidly supported by said plates, and a plurality of wheels rotatably mounted on the shaft, and constructed of blades and peripheral rims, the blades of alternate Wheels being inclined in opposite directions to the planes in which the Wheels are disposed, and the rims of all the wheels being tapered in the same direction.

5. The combination with a cylindrical shell, of plates mounted in the ends thereof, each formed with a plurality of openings, a shaft supported by the plates, and a plurality of Wheels rotatably mounted on the shaft, each constructed with inclined blades, one of said plates having a central threaded aperture, and the corresponding end of the shaft being threaded and secured in said aperture.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.
